Hybrid tea rose plant named &#39;meimarkize&#39;

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided that forms at mid-season abundantly and substantially continuously attractive yellow-green blossoms suffused with pink possessing a light fragrance wherein the numerous petals are positioned in a quartered manner. The buds are substantially globular-shaped. The vegetation is strong and attractive green foliage is formed. The plant forces well and is particularly well suited for cut flower production under greenhouse growing conditions.

BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Hybrid Tea Rose Plant

VARIETAL DENOMINATION

cv. Meimarkize

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the ‘Meisatex’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the cross of the ‘Meikola’ variety (U.S. Plant Pat. No. 5,607) and the ‘Keidargo’ variety (non-patented in the United States). ‘Meisatex’×(‘Meikola’×‘Keidargo’).

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new Hybrid Tea rose plant of the present invention:

-   -   (a) forms strong vegetation,     -   (b) forms substantially globular-shaped buds,     -   (c) forms at mid-season abundantly and substantially         continuously attractive yellow-green blossoms suffused with pink         possessing a light fragrance wherein the numerous petals are         positioned in a quartered manner,     -   (d) displays attractive green foliage,     -   (e) forces well under greenhouse growing conditions, and     -   (f) is particularly well suited for cut flower production under         greenhouse growing conditions.

The new variety well meets the needs of the horticultural industry and performs well under greenhouse growing conditions. No disease problem has been observed during observations to date when the new variety was being grown in greenhouses.

The new variety can be readily distinguished from its ancestors. For instance, the blossom coloration is considerably different from that of the ‘Meisatex’, ‘Meikola’, and ‘Keidargo’ varieties. More specifically, the ‘Meisatex’ variety forms orange-red blossoms, the ‘Meikola’ variety forms Venetian pink blossoms, and the ‘Keidargo’ variety forms dark red blossoms.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named ‘Meimarkize’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were approximately one year of age and were observed during May while growing on Rosa indica Major understock and growing in greenhouses at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph, as is a standard color comparison.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of one-year-old plants during May which were budded on Rosa indica Major understock and growing in greenhouses at Le Cannet des Maures, Var, France.
